Var. edentula Moq.— ^Vith the type at Vazon, and Botdeaux, 

 Guernsey. 



Var. curta West. — Generally distributed in Guernsey, Alderney, 

 and Sark, intermixed with the type, and always connected with it by 

 intermediate forms. 



P. muscorum L. — Jersey (Duprey). Guernsey, not uncommon, 

 but rather local ; especially at Vazon Bay and Lancresse, under stones 

 and amongst grass. Alderney, in many places, plentiful where found. 



Vertigo antivertigo Drap. — Generally distributed along the 

 southern cliifs of Guernsey, sometimes plentiful; common also in 

 marshy ground at Cobo and Vazon Bay. Frequent under stones in 

 all the cliff valleys in Alderney. 



V. pygmaea Drap. — Jersey (Duprey). Guernsey, locally plentiful 

 at Bordeaux Harbour and about Richmond ; also taken at the Cor- 

 biere and near King's Mills. Common under stones in Corbelets 

 Quarry, Alderney, and at Clanque Bay. 



V. edentula Drap. — Jersey (Duprey). Rare in Guernsey ; Bor- 

 deaux, Petit Bot, and Saints' Bay. 



Balea perversa L. — Jersey (Duprey). Guernsey, on mossy walls 

 and tree trunks in all parts, but not common. Alderney, in several 

 places ; also in Sark. 



Clausilia rugosa Drap. — Common in all the islands. The size is 

 smaller on an average than that of English specimens, and decollate 

 shells are not infrequent. An example from Clarence Battery has the 

 last whorl disunited, exactly like some of the AVest Indian Cylindrellce. 

 The following varieties are of occasional occurrence with the type — 

 Var. tumidula Jeffr. 

 Var. gracilior Jeifr. 

 Var. everetti Miller. 



Cionella lubrica Miill. — More or less common in Jersey, Guern- 

 sey, Alderney, and Sark. 



Var. fusca Moq. — Occasional in Guernsey with the type. 



Caecilioides acicula Miill. — Jersey, in a garden (Duprey). Re- 

 corded for Guernsey by Jeffreys, but we have not met with it. 



Succinea putris L. — Common in suitable spots in all the islands 

 except Herm, but apparently all belonging to the variety below. 



Var. ferussina Moq. — We have not seen anything like typical 

 specimens of S. putris, and incline to doubt the existence of the type, 

 at any rate in Guernsey and Alderney. Specimens of the prevailing 

 form were called vax. ferussitia by Mr. Taylor of Leeds (seey. Conch., 

 vol. 4, p. 273), and with this determination we agree, after a careful 

 study of the figures and descriptions in Baudon's "Monograph " (pp. 

 20, 21). There seems to be no difference except in size between this
